PeteWilbyTriathlOn is accredited by Beyond Swim to the highest standard.  This means we provide a marked-out course and the best safety procedures and trained staff at all times.  Our team consists of qualified triathlon and open water swimming coaches and teachers as well as first aiders and beach lifeguards.  


Our coached group sessions are designed to help people excel.  We run an experienced open water swimming (OWS) squad from May to October in the sea.  From October to April we go to the pool for a 60-minute conditioning session.  The experienced OWS squad is for all swim speeds who are confident swimming front crawl in the sea for one hour.  We normally have four groups of similar speed swimmers in the sea.  In the pool, through winter, we have the whole pool split into four lanes.


PeteWilbyTriathlOn is for everyone.  We have a beginner open water swimming session for swimmers who are new to the open water.  This session is normally split into two groups.  A group of complete beginners who aim to master front crawl and a group of swimmers who can do front crawl but are new to sea swimming or not quite ready for a 60minute training session.  Beginners who feel comfortable doing a training session can also join the pool squad through winter.  Our aim is to facilitate swimmers’ progression and support the graduation through our squads.
